Is It Healthy To Eat The Same Thing Every Day? Even If It's Nutritious?

Sometimes, eating the same thing every day, especially if it’s nutritious, seems like a good idea.Having something like egg whites, yogurt and toast for breakfast, and chicken, broccoli and rice for dinner helps with meal preparation and simplifies one’s life. 

It can also aid in maintaining energy levels. For example, an athlete friend of mine eats the same thing every day at the exact same time (3:30 p.m.) to “secure his energy levels.” Two hours before his workout, he eats chicken, rice and rice cakes.
